How Are Ocean Ridges Formed?

Answer

Ridges within the ocean floor are caused by a number of underwater activities. These include movement and shifting of tectonic plates, gushes of magma due to the pressure underneath (the magma cools beneath the ocean forming ridges), symmetrical rock formation and from the deep sea trenches that form as a result of the shift of the continental plates.

The Ocean ridge was formed through the process of tectonic plate movement which forces lava through the created cracks and when the lava cooled it forms the ridge. Ocean ridges are formed from the uplift of newly formed oceanic crust by rising magma.
